Made for expedition use, the Peregrine's wider hood opening provides extra comfort during extended tent-bound conditions. On the Himalayan peaks the Peregrine and Ptarmigan (used with down clothing) have kept climbers warm at 40 below, caught without a shelter at 28,000 feet. In Alaska, the Peregrine has been the most popular mummy bag for expeditions on just about every peak.  The Peregrine now uses waterproof and breathable Pertex Shield EX outer-shell fabric.
